8 Claims. (Cl. 2286) This invention relates to a method of and apparatus for the assemblingof sectional textile rolls, and to a novel type of assembly unit between the various roll sections which eliminates many of the undesirable features present in rolls now used in the textile art.

Complete rolls of the type to which this invention applies are small in diameter but when assembled into a' roll unit they may be from twenty to thirty feet or more in length, and because of mechanical difiiculties must necessarily be made upof a number of relatively short sections, and have a number of bearing surfaces or journals to insure a workingalignment.

In the rolls now being used almost universally the journals are apart of the roll section,;and the sections are joined by either a threaded connection or a more or less loosely pressed mortise joint, to be illustrated and described hereinafter.

This type of connection causes back-lash, or a reciprocal circumferential play between the sections, which is responsible for uneven feed of the cotton fibers between-the fluted portions; of the rolls. The journals have a natural tendency to wear out and,since they are an integral part of the roll sections, this =means considerable shutdown and replacementexpense.

It is an object ofthis invention to furnish a roll .connection' which will eliminate back-lash by causing the assembly to approximate a roll of unitary character, the joints being forced together under high pressure.

It is another object to furnish a joint which may be used for restoration of those rolls now in use which have had their journals worn until no longer of practical use.

It is a further object to supply means for forming this connection rapidly and accurately, one form of such means comprising the novel hydraulic press illustrated in the drawings which form a part of this application.

Further objects of theinvention will more fully appear as the description-proceeds.

is a 'stationarybody or casting in which'and 1 through which move the power .and assembly units. Preferably integraljwith casting 20 are the twin cylinders 21 and areservoir tank 22 for the fluid which operates the various pistons to be later described. Tank 22 is covered and sealed" by a cover 23, and vented by a valve 24. c In the cylinder 2i operate pistons 25, to whichare connected piston rods -26 which are secured rigidly-to the movableportion of the machine. This portion includes a crosshead 27 to which the rods 26 are directly attached. The crosshead 27' is carriedjon guide rods--28 which slidelongitudinally through the casting and,are connected on the opposite or rear end of the casting from the crosshead by :a cross bar 29 to which is also rigidly connected a piston rod 30. This rod terminates in a piston head 31operating in a cylinder 32 for a purpose to be hereinafter described. r H

As shown in Figure 3, a tubular passageway 33 extends through the'metalof the body 20 be-jtween the cylinders 21, and is designed to contain the roll' sections 34 during the operation of, the machine. The passageway 33 is provided at the forward end of the body or cylinder casting with a bushing 35, the inner diameter of which is the same as the diameter of the fluted portions of the roll sections 34, and is adapted toform a close fit therewith. Bushing 35- is removable and interchangeable with another having a larger or a and moves with the latter.

changeable with bushings having larger or smaller openings therethrough. The bushing 39 is;secured by a screw member 40 similar to the securing pin 36. 2

Suitably connected, as by screw threadsto the box heads 41 and 42, are sections of tubing 43 and 44, respectively, through-which extendthe roll sections 34. The tube. 43 is also secured as.

at 43 in suitable manner to the cylinderblock, and remains stationary with it, while thetube 44 is suitably secured as at 44 to the crosshead 27, The box-heads 41 and 42 are similar, and are positioned one at the-forward end of the machine and'the other at the rear end thereof. One of them is shown in detail in Figures 4 and 5, and a description thereof will suffice' for both. Itcomprises a plate 45 having-a sleeve 45 into-which'is-screwed (or otherwise secured as by-splitting and bolting the sleeve sections together as at 53) the outer end of the tube- 44. The plate carries extensions 46 .on which are'pivoted levers 47. Extensions 48 -on the levers 47 engagein recesses inclamping jaws 49, which jaws are slidable toward and away from each othena'ndhave semi-circular indentations'50 designed to clampiabout and hold securely'the depressed portions of roll sections 34. The jaws 49" are slidable in a slot. in the plate 51, through which plate extends a further continuation '52 of passageway 33. The plate 51 is secured byscrews to the'plate 45 as illustrated, and

the jaws are removable ion-interchanging with other jaws of greater or less length, and with greater :orless radii 'of indentations 50 toaccommodate theparticular size of- 'roll assembled. a

' It will thus be seen that from one box head through the other there is a continuous passageway extendingthrough the machine, through which passageway the rolPsections may progress section being in uninterrupted alignment as they are assem bled. 1 e

' Referring particularly to Figures 1, 2 and 6, the power which drives the'piston heads 25 and 31 is "derived from hydraulic pressure generated by means of a pump which includes-a handle 54 pivoted at 55 to a link 56, which is in turn pivotally connectedas at 56 to an extension 57 on the cover 23. Pivoted to the handle 54 at 58 is a pump rod 59 which operates in a cylinder 60. A' valve 61 which opens inwardly from the reservoir -22, and which is positioned in sump 62, allows oil from the'reservoir to flow into cylinder 60 whenthe rod is raised and prevents its return when the rod is driven downward by the handle their forward ends are connected by the cross pipe '71. From the pipe 70 extends downwardly a vertical pipe 72, which opens into the cylinder 32, and from pipe 71 a vertical pipe 73 leads to a pressure gauge [74, and to a passageway '75 (see Fig. 6) which divides into ducts 76 opening into the cylinders 21 between the forward ends thereof and -thepiston -25; n

The method of reciprocating the movable parts of the machine, and the method of assembling ;the roll sections may now be described. Figures 8 and 9 illustrate one of the methods now in common practice over which this invention is an improvement. In such figures, the roll 77 is provided] witha journal 78, and a squared shaft '79 madeiin'tegral with it, the shaft being fitted by sliding fit, and more or less loosely into a squared hole80'in the end of the adjacent section 81 of the roll. The figures show the sections separated. According to my invention the rollsec- 'tions illustrated-in-Figures wand 11 are prepared for joining bythe cylinder neck-82 which" I'pse,

by having cylindrical openings-83 provided their adjacent ends, which-openings are designed to make an extremely'tight pressedfit with the neck 82 which is to join the rollsections. The neck 82 is preferably of hardened tool steel','-because it is'tobecome one of theijourn'als of the 'completedroll, and is machined'to make a very closefit with the cylinder apertures 83 of the roll sections 34. This forced fit requires a considerablepressure to secure, and the machine will supply this pressure aswill morefully appear.

In. assembling a roll, "twosections 34 are inserted in'the machinaone'through the'opening 52 'in'the box head 41 from the rear ahdthe other through opening 52 in the'box head-42-from the front'of the machine. The first of these is pushed through bushing 45 tube 43,;passageway 33,-:and bushing 35," andout on the oth'er 's'ide' 0f the cylinder casting until it projects therefrom-about three-fourths of -an inch, as shown in Figures 2 and 3. It'is" assumed that the crosshead is'in its outermost position-withreference to the -cylinder block, "the pistons 25 being at "theforward ends of the cylinders 21 and the piston31jbeing at the forward end of the cylinder 32. The other roll section ispushed thr'ough busliing'45 tube 144', bushir'lg' 39 in the 'cro's'shead 2'75-fihti1 it also projects aboutthree-fourths of an'inch. *The handles 47 of botl'i'box heads 'ai'eth'en turned until the jaws 49 lock' about'thedepressedportions of the roll sectionsy'a'nd holdthemimmovable. When the parts are inthisposit'ion, the distancebetween the adjacenten'ds of -the roll sections is sufiicient to receive the-neck 82.

The pump isthen operated to; move the crossheadtoward the cylinder, the oil flow being-hereinafter described, with the ends 0f the heck aligned with the openings'83 'of the -"adjacent roll sections, thus forcing the endsof the neck into the roll sections. The movement "ofthe crosshead continues until a it is"'brought' to a {stop by the engagement ogf-stops 37 on the crosshead with the stops 38 on-the cylinder block. 'Injoining the'first two sections of a roll, a fine adjustment is always made'forthe distance to 'beleft between the adjacent ends'of-thes'ections after the'neck is-pressed in, so that'i'every subsequent section is spaced the sameytovery close limits, and 'this, without" having to'fmeasure each' section. "I'his is done byjadjusting the tube ;44 to lengthen 'or shorten-the distance' bettveen the box head 45 and the crosshead 27, so that when the 3 space between the ends ofthe roll sections is v 'i,9s9,c42 just right (after the neck is pressed in) the stops 3'7 will be squarely against the stops 38 of the cylinder head. To secure this adjustment, the tube 44 may have a right and left hand thread and may be turned in the one direction or the other, so as to increase or diminish the distance between the front box head and the crosshead.

' It will be understood that if the split sleeve construction is used in securing the tube to the crosshead and forward box head, the sleeve will" be loosened when the adjustment is made and the oil being forced through the pipe 64, and so .to pipe 65. Here its flow is stopped in one direction by the closed valve 67, and hence it passes {through valve 66 to pipe '71, and around to the valve 69, which is also closed. Therefore, its

only passageway must be down pipe '73 to passageways '75 and '76, and thence to cylinders 21, where it forces back the pistons 25. This movement of the pistons, through their connection by means.

of the rods 26 with the crosshead, draws the latter toward the cylinder blocks until the stops 3'7 contact with the stops 33. The gauge "74 will register the pressure during this operation. During this motion the guides 28 havemoved back with the crosshead carrying with them the cross bar 29 and piston rod 30,of course moving the. piston head 31 towards the rear end of *the ,cylin-:

'der 32. This movement will cause the oilwhich has been dormant in cylinder 32 to move upwardly through pipe '72 to pipe '70. Here it flows in both directions, being stoppedby the closed valve 67' in pipe 65, and allowed to pass through pipe:-

8'7, valve 68 which is open, and through pipe 86 back into the reservoir 22.

At the end of this movement of the crosshead the joint has been completed and it is necessary to prepare for the next. The jaws 49 on the box heads are released, the joined sections are drawn rearwardly through the central passageway until the unconnected end of the section which was in the pipe 44 is now contained in the cylinder block and pipe 43, with such unconnected end extended outwardly about three-fourths of an inch as before. The jaws 49 of the rear box head may now be closed so as to bind the'roll section extending out through such box head. The valves 66 and 68 are now closed, and the valves 67 and 69 opened, and pressure is created by the pump. As before, oil is forced in the tank through the pipe 64 into the pipe 65, but now it is stopped by the closed valve 66, and so flows rearwardly through valve 6'7 and pipe 65, to pipe '70, thence through pipe '72 to cylinder 32 (its flow through pipe 8'7 being stopped by the closed valve 68). Accumulating in the cylinder 32 it forces the piston 31 forward. This movement causes the cross bar 29, guide rods 28, crosshead 2'7, and the pipe section associated therewith to move forwardly and away from the cylinder block. The pistons 25 being connected with the crosshead, are also drawn forwardly, thus forcing oil out of the cylinders through the ducts '76 and pipe '73, to pipe '71. The valve 66 being closed, the oil passes through the valve 69 of pipe 8'7, and by reason of the valve 68 also being closed, thus necessarily passes through pipe 66 back to the reservoir. Thus the parts are again returned to the open position illustrated in the drawings.

A new roll section is now inserted in the pipe 44,.the jaws of the forward box head are closed about the roll section, a new neck is lined up with the adjacent roll ends, the valves are again reversed, and thepump operated, to again drive the crossheadltoward the cylinder block and thus complete the second joint. The adjustment for the distance to be left between the adjacent roll 'ends after the joint is made, having already been secured in the first operation, no further adjust- I ment is necessary. In this manner, the roll sec-" tions are assembled one after the other, the sectionsbeing inserted in the forward end of the machine, and the joined sections being pulled through the rear end of, the machine, the sections thus passing through the machine from one end to the other during the process of being joined.

It'will be observed that the bushings provided in the machine, support the sections in properly aligned position with reference to each other, and that the movable parts of the machine are maintained in proper alignment with the stationary parts thereof by the guide rods. Thus it is only necessary to feed the roll sections into one end of the machine and pull the joined sections out of the other end as the machine is operated, it not being necessary. to pay any attentionto the alignment of theroll sections, nor to constantly ,measure the distance left'between adjacent ends of joined sections.

I have found that by constructing the joints, with cylindrical necks having a pressed fit with the cylindrical openings in the roll section ends,

an extremely rigid and tight joint is rrrgde one.

in which back-lash will not develop, as with other types of joints now in common use, and one in which the necks may form the journals of the rolls, thus eliminating the necessity of-providing the rolls with special journals and with squared shafts, such as have been illustrated in Figure 8,

and a joint is made which renders the entire roll from one end to the other extremely rigid and straight. I
